The file with a .GEO extension (in our case – MASTER.GEO) is responsible for creation of the model’s geometry. The room is built by defining fixed points of given coordinates (CORNERS section), which can be corners of planes (PLANES section) of given sound-absorbing and sound-scattering properties (lines starting with the ‘ABS’ abbreviation). The lines we do not intend to use are followed with a semicolon – it makes the program ignore them. More data on topic of this file can be found in further parts of this course.
